函数定义不声明参数（不能查找错误）

Question

我是C ++的初学者。所以我找不到错误。 ＆＃34; string* toolHolder＆＃34;存在问题。 。错误信息是;

  17bigthree.cpp:29:10: error: function definition does not declare parameters
  string* toolHolder:
          ^
17bigthree.cpp: In constructor ‘GCharacter::GCharacter(std::__cxx11::string, int)’:

这是一个什么样的问题？我看起来一样的问题，但我无法解决问题。

#include <iostream>
#include <string>
#include <new>


using namespace std;

    GCharacter(const GCharacter& source); //copy constructor

    GCharacter& operator=(const GCharacter& source); //overloaded assignment

    ~GCharacter();  // Destructor

    void insert(const string& toolName); // insert a new tool into the tool holder
